' ments in Drop-down Small-Arms, of which the following is a specification.

This invention relates to improvements in drop down small arms, and has reference to s in which the main springs are compressed by the closing of the gun. It is fully recognized that in actions of this kind, in which the closing of the gun is made to operate and put into compression the main springs for the hammers, that the said spring force has a tendency (as far as possible) to cause a leakage at the breech face, and further, that with the opening and closing of the gun under these conditions, when not fired, or partly fired, the spring pressure causes increased friction and wear upon the several parts, which tends to produce a slackness and impair the desired perfect close fitting at the breech joint, and the object therefore of this invention is to provide improved means whereby upon the final closing of the gun, all upward spring pressure upon the barrel lump, or tendency to 0 en the gun thereby, shall be removed.

T 's my invention is applicable to an action in which a lever (or levers),and which for the sake of description I will term the lump cocking lever,is employed suitably carried in the action body, and whose one end is operated by the downward movement of the lump upon the barrel portion, so that the other end of said lever puts the main spring into compression ready for firing, and it is in reference to means in association with the former end of this lever (or levers) that this my invention particularly applies, that is to say, I provide that at the termination of the downward movement of the said lump, or special lumps or projections upon or operated by the barrel portion,

the end of the lever shall pass to a position upon such lump or similar part that is circular to, or nearly so, the center of the body joint, so that the spring pressure then acting upon the said lever shall exercise practically no upward pressure upon the barrel portion, but at the same time the said lump or projection retains the lever in the position to preserve the spring pressure upon the hammer.

I attain this object by the mechanism illustrated in the accompanying drawings, in

Figure 1 is a side view of the invention in which the gun is shown open, and in which the forward end of the lump cocking lever is made to engage with the under part of the back portion of the lump; Fig. 2 being the same arrangement as seen when the gun is closed. Fig. 3 is a side view of the invention in which the gun is shown open, and in which the forward end of the lump cocking lever is made to engage with a special lump formed upon the barrel portion Fig. 4 being the same arrangement as seen when the gun is closed. Fig. 5 is a side view of the invention in which the gun is shown open, and in which the forward end of the lump cockinglever is made to engage with a lump connected to the action body, but operated by the barrel portion; Fig. 6 being the same arrangement as seen when the gun is closed. Fig. 7 is a side view of the invention in which the gun is shown open, and in which the forward end of the lump cocking lever is made to engage with the under part of the front portion of the lump; Fig. 8 being the same arrangement as seen when the gun is closed. Fig. 9 is a side viewshowing the gun closedin which the lump cocking lever is again modified in shape to engage with a lump or projection formed upon the barrel portion; ig. 10 being a plan view of such lever. Fig. 11 shows a side view of a modified form of lump cocking lever made to act upon a special lump pivoted to the action body, but operated by the barrel portion. Fig. 12 shows a side view of a further modified form of lump pivoted to the action body which is acted upon by the closing of the gun, which said lump acts upon the lump cocking lever.

Referring now to Figs. 1 and 2 1-14 is the action body. 15 is the barrel portion pivoted thereto at the usual joint 16. 17 is the hammer pivoted at 18. 19 is the main spring, which is carried in what I may term a springboX lever 20, which is pivoted at 21. 22 is the sear lever. These parts in and of themselves do not constitute any part of this my invention, but are described for the sake of explanation. 23 is the lump cocking lever, which is pivoted at 24 to the action body. The rear end 25 of this lever ismade to act upon the lever 20 in order to compress the spring 19 in order to put the hammer 17 under stress. The front end 26 of the lever is brought into touch with the back lump 27, but in such a manner that when the gun is closed, as seen in Fig. 2, the said end 26 passes slightly in rear of the surface 27 a of the lump 27. Hence when passing from the open position to the closed position, the said lump 27 presses down the lever 23 for the purpose hereinbefore named, until at the last moment the end 26 assumes the position shown in Fig. 2, where it will be observed that there is no possibility of the end 26 rising, nor is there practically any upward pressure therefrom upon the lump 27.

Referring now to Figs. 3 and 4, it will be seen that the lever 23 is slightly modified in shape to that already described, so that its front end 26 is made to engage with the lump 28 formed upon the barrel portion. Hence when the gun is closed, the lump 28 presses down the end 26 until just at the end of the said closing movement the end 26 passes in front of the surface 28 upon the said lump keep the lever 23 in its pressed down position, while there is practically no upward pressure upon the barrels therefrom.

Referring now to Figs. 5 and 6, 29 is a lump or projection, which is pivoted at 30 to the action body 14, the said lump further being moved downwards upon its pivot by the barrel portion 15, so that when the gun is closed the end 26 of the lump cocking lever is pushed downwards, as before described, until just at the final movement the said end passes to the front of the surface 29 with the same result as before described.

Referring now to Figs. 7 and 8, in this case I have shown the lump cocking lever somewhat modified in shape, such for instance that would be suitable for putting the main spring into compression when such spring was carried in a lever 20 as shown in dotted lines, in which case the end 25" of the lever operates the spring mechanism. In this case the end 26 of the lever is made to be acted upon by the front lump 31, so that again upon the closing of the gun the said lever is depresseduntil at the final closing movement the end 26 passes just in front of the surface 31, when it will be noticed that the before named conditions as to the retention of the lever, and the absence of upward pressure is maintained.

Referring now to Figs. 9 and 10, in this case the lump cocking lever 23 is modified somewhat in shape, but acting upon the spring mechanism similar to the lever shown in Figs. 7 and 8, that is to say, the part 25 causes the compression of the main spring. The forward end 26 of the said cocking lever is made to pass behind the surface 28, similar to that shown and described in reference to Figs. 3 and 4.

Referring to Fig. 11, it will be seen that the lump as shown and described at 28 in consequently the said lump will- Figs. 3, 4, and 9, may be pivotally carried upon lever 32 pivoted at 33 to the action body 14 in a similar manner to that shown and described in Figs. 5 and 6. The action and, operation of the lever 23 in reference to said lump 28 will be clearly understood from the descriptions already given.

Referring to Fig. 12, it will be seen that the lump 36 may be pivoted to the action body at 37, and be made somewhat in the shape of a lever, so that the part 38 may enter an opening 39 in the fore end 40, which latter is of course secured to and forms as it were one with the barrel portion of the gun. Hence when the gun is being closed the underside of the lump 36 presses down the end 26 of. the lump cocking lever 23, until at the final movement of the said closing the end 26 passes in front of the surface 36*, in av similar manner, and with a similar result to those before described.

From the foregoing it will be-seen that in each casethe surface upon the cooking lever and the surface upon the operating lump, which come in contact with each other, each assume a position relatively opposite to each other, thus giving the desired function of the; lump to the lever, that isto say, the path of movement of the one somewhat crosses that of the other, as: shown for instance by the dotted lines 34 and 35 in Fig. 2. Thesame fact exists in the other figures shown.

What I claim as my invention and desire to secure by Letters Patent is 1. In drop down small arms, the. combination with the main spring compression lever, of a locking member movable with the barrel and havinga working face arranged in such relation'with respect to oneend of'the lever whereby upon the closing of the gun said working face afteractuatingthe lever: to compress the main spring will bear against the saidend of the lever to prevent mo vement thereof so as to overcome any tendency towards the openingof the gun by pressure of the main spring.
